Sažetak

This study presents the application of multipole expansion to calculate the roll damping of the rectangular box. The N-parameter Lewis form was used to follow the rectangular cross section. The Ursell-Tasai method was employed to deal with non-circular cross section. The added mass and damping coefficient of the sway, heave, and roll motion were calculated. BEM code was developed to compare with the results. Experiment was done to verify the flow field calculated from the multipole expansions.
